We are presently running NOD 32 V2.7 Standard edition on 5 computers and also on our Network Attached Storage (NAS) device. This morning, I renewed our licenses but was told that we must now use the business edition because of the NAS device. My questions are as follows: 1) On the client workstations do I have to uninstall V2.7 prior to installing V3 or will it upgrade the older version? 2) On the NAS device will I have to update the program or can I leave V2.7 and just enter the new username and password? I would prefer not messing around with software on the NAS device unless it is absolutely necessary. Thanks in advance for any help on these questions.
